We’re passionate about all things fermentation.
From Lab to Cellar: Aotearoa's Yeast Specialists
HUMBLE BEGINNINGS
Froth Technologies was founded to bring yeast production to Aotearoa, giving Kiwi brewers access to fresh, local liquid yeast without the long delays and hold-ups of importing. We started out in a shared commercial kitchen, pitching our first strains into tiny tanks for one-off brews.
These days, we’re running New Zealand’s first dedicated yeast lab, supplying craft breweries, homebrewers, distillers and cider makers across NZ and afar.
We grow fresh high-performance yeast strains, brewed for local conditions and backed by science. Whether it's reliable workhorses or funky wildcards, we’ve got the goods to help your beer hit the mark.

OUR IMPACT
At Froth Technologies, our purpose is brewed into every cell of yeast we grow. Achieving our Ekos Climate Positive re-certification reflects a long-term commitment to understanding, reducing, and responsibly addressing the carbon impact of our operations.
Sustainability is embedded in how we make decisions, how we work with suppliers, and how we engage with customers across the commercial brewing and homebrewing sectors. By communicating our climate commitments transparently—through product labelling and customer communications—we aim to empower our customers to support responsible, climate-conscious businesses.
Our certification journey is also deeply connected to our workplace culture, helping guide our ambition to become one of the most sustainable yeast laboratories globally. While economic pressures within the brewing industry have recently constrained the pace of some initiatives, sustainability remains central to Froth Technologies’ growth strategy, including as we expand our product range and enter international markets in Aotearoa and beyond.
Despite challenges in the brewing sector, Froth Technologies has made meaningful progress. Using FY22 (1 March 2021 – 28 February 2022) as the base year, we have reduced our absolute emissions by 10.38% and achieved a 45.06% reduction in emissions intensity per gross revenue.
These improvements are largely driven by significant reductions in purchased electricity, staff commuting, business waste, and fuel- and energy-related activities. We continue to prioritise further reductions in freight, business travel, and stationary combustion—areas where collaboration and innovation will be key.
We offset 120% of emissions with certified carbon credits and additionally, we support biodiversity conservation with biocredits. Carbon credits are sourced from a landfill gas-to-electricity project in Turkey and retired in the Verra Registry. We also support biodiversity outcomes through SDUs / Ekos SD BioCredita Units contributing to conservation at Sanctuary Mountain Maungatautari. These units are not offsets.
OUR PROCESS
Our yeast propagation process starts with (just) a few million cells. Pure mother cultures are pulled from our -80°C cryo freezer and streaked on to agar plates. Cultures are hand picked from there and innoculated into sterile liquid growth medium. The yeast propagation is nursed into life (and growth) with precise temperature, nutrient, and agitation controls, and checked daily to monitor vital metrics. The propagation is fed daily with increasing volumes. From a start of only a few million yeast cells, the culture grows to a population of up to 100 trillion cells - enough to ferment over 10,000L of beer!
Purity of cultures is achieved through high levels of sterility and hygiene, and this is monitored with strict quality assurance protocols throughout. From the first streak to the final package, Froth Technologies’ yeast is grown with the utmost care and attention, so you can be confident that nothing but the best goes into your tanks.
OUR PASSION
We’re proud to be an independent, sustainability-focused business, supplying yeast and fermentation products to businesses big and small. Our work has picked up national awards for innovation and is trusted by some of the country’s most awarded breweries.
Whether its’ dry yeast or liquid, custom propagations and yeast banking; Froth Tech is your one-stop-shop to help your fermentations thrive.
